ABSTRACT
Left atrial appendage (LAA) occlusion has emerged as an al- ternative to oral anticoagulation in non-valvular atrial fibril- lation. The success rate is high, but we are still facing some challenging LAA anatomies that may increase the risk of sub- optimal results. These images show that the Amplatzer steer- able sheath is useful for LAA occlusion, especially in cases with challenging anatomies. Small variations of the distal end angle can improve the success rate and reduce complications.

OBJECTIVES: We sought to explore the immediate results of Titan2 stent implantation in small coronary arteries, as well as the incidence of major adverse cardiac events (MACE) at six months follow-up. BACKGROUND: The safety of Titan2 stent has been confirmed in several studies in real-life unselected populations. METHODS: We enrolled 311 consecutive patients admitted for percutaneous intervention for at least one significant (50%) de novo lesion in a native small coronary artery (2.0-2.75 mm). All lesions were treated with Titan2 stent implantation. Patients were prospectively followed up for at least six months. The primary endpoint was MACE at six months follow-up [death, myocardial infarction (MI), or target vessel revascularization (TVR)]. Secondary endpoints included angiographic and clinical procedural success, in-hospital MACE, target lesion revascularization (TLR) during follow-up, and stent thrombosis. RESULTS: The mean age was 67.3 +/- 10.9 years (65.9% males). A total of 356 Titan2 stents were implanted in 353 lesions. Angiographic and clinical procedural success was achieved in 344 (97.5%) patients. No case of in-hospital MACE or acute stent thrombosis was reported. Clinical follow-up was completed for an average of 8 +/- 2 months. Two patients (0.7%) died, and 6 (2.1%) developed MI. TLR was performed in 12 (4.2%) and TVR in 16 (5.5%) patients, all were clinically driven. Cumulative MACE occurred in 20 (6.9%) patients. One patient suffered subacute stent thrombosis, but no late stent thrombosis. CONCLUSIONS: Titan2 stent implantation in small coronary arteries achieves excellent immediate outcome, with a low incidence of MACE at mid-term follow-up.
